Overview_Description: 


Entity_and_Attribute_Overview: 


   The minor code in the info file is not broken down any further than          
   0201 - railroads. There is no distinction between those rails in             
   a tunnel, on a bridge, abandoned, etc. Also, there is no code                
   indicating light rail.
